Clostridium is a genus of anaerobic, Gram-positive bacteria. Species of Clostridium inhabit soils and the intestinal tracts of animals, including humans. [ 1 ] This genus includes several significant human pathogens , including the causative agents of botulism and tetanus .
Clostridioides difficile (syn. Clostridium difficile) is a bacterium known for causing serious diarrheal infections, and may also cause colon cancer. [4] [5] It is known also as C. difficile, or C. diff (/ s iː d ɪ f /), and is a Gram-positive species of spore-forming bacteria. [6]
Clostridioides difficile infection [5] (CDI or C-diff), also known as Clostridium difficile infection, is a symptomatic infection due to the spore-forming bacterium Clostridioides difficile. [6] Symptoms include watery diarrhea, fever, nausea, and abdominal pain. [1] It makes up about 20% of cases of antibiotic-associated diarrhea. [1]
Most species of the genus Clostridium are saprophytic organisms that ferment plant polysaccharides [2] and are found in many places in the environment, most notably the soil. However, the genus does contain some human pathogens (outlined below). The toxins produced by certain members of the genus Clostridium are among
Clostridium perfringens (formerly known as C. welchii, or Bacillus welchii) is a Gram-positive, bacillus (rod-shaped), anaerobic, spore-forming pathogenic bacterium of the genus Clostridium. [ 1 ] [ 2 ] C. perfringens is ever-present in nature and can be found as a normal component of decaying vegetation, marine sediment , the intestinal tract ...
Clostridium septicum is a resident bacterium of the human microflora, however it can be found in almost any anoxic habitat in which exists organic compounds. [4] Under unfavorable conditions, C. septicum forms endospores allowing it to survive under harsh conditions such as extreme temperature, dry land, and nutrient-deficient habitats.
The Clostridiaceae are a family of the bacterial class Clostridia, and contain the genus Clostridium.. The family Clostridiaceae (scientific name) defined by the taxonomic outline of Bergey's Manual of Systematic Bacteriology contains as its core the genus Clostridium (sensu stricto), as well as Acetivibrio, Acidaminobacter, Alkaliphilus, Anaerobacter, Caloramator, Caloranaerobacter ...
Genus Romboutsia: Clostridium lituseburense, reassugned in 2014. Genus Sarcina: Clostridium maximum and C. ventriculi. Originally described in Sarcina, proposed to be moved to Clostridium in 2016 but remained due to Sarcina being the older genus. Genus Terrisporobacter: Clostridium glycolicum and C. mayombei, reassigned in 2014. Family ...
